Patent number: 8870538Abstract: A gearbox assembly includes a first face gear driveable about a face gear axis in a first direction by at least one first pinion gear and a second face gear driveable about the face gear axis in a second direction opposite the first direction by at least one second pinion gear. A thrust bearing is located between the first face gear and the second face gear. The first face gear is configured to drive rotation of a first shaft in the first direction and the second face gear is configured to drive rotation of a second shaft in the second direction. Further disclosed is a power train for a rotary wing aircraft having a gearbox including a first face gear rotatable in a first direction and a second face gear rotatable in a second direction opposite the first direction.Type: GrantFiled: January 15, 2014Date of Patent: October 28, 2014Assignee: Sikorsky Aircraft CorporationInventor: Todd A.

Publication number: 20120181377Abstract: A vibration control system includes four mass discs located at a central axis and rotatable thereabout. Each mass disc includes a mass secured thereto wherein rotation of the four mass discs creates a vibratory force output. A power transfer assembly is located between adjacent mass discs of the four mass discs and is configured to transfer rotational energy between the adjacent mass discs. The power transfer assembly includes a power transfer shaft rotatable about a power transfer shaft axis and a power transfer disc connected to the power transfer shaft and in frictional contact with each of the adjacent mass discs at a contact point. When the power transfer shaft is rotated, a radial location of the contact point at each of the adjacent mass discs relative to the central axis is changed, altering the vibratory force.Type: ApplicationFiled: January 10, 2012Publication date: July 19, 2012Applicant: SIKORSKY AIRCRAFT CORPORATIONInventors: Erez Eller, Todd A.

Patent number: 7942365Abstract: A transmission gearbox for a rotary-wing aircraft includes a main gearbox and a variable speed gearbox in meshing engagement with the main rotor gearbox. The variable speed gearbox permits at least two different RPMs for the main rotor system without disengaging the engine(s) or changing engine RPMs. The variable speed gearbox includes a clutch, preferably a multi-plate clutch, and a freewheel unit for each engine. A gear path drives the main gearbox in a “high rotor speed mode” when the clutch is engaged to drive the main rotor system at high rotor rpm for hover flight profile. A reduced gear path drives the main gearbox in a “low rotor speed mode” when the clutch is disengaged and power is transferred through the freewheel unit, to drive the main rotor system at lower rotor rpm for high speed flight. The variable speed gearbox may be configured for a tail drive system that operates at a continuous speed, a tail drive system that changes speed with the main rotor shaft or for no tail drive system.Type: GrantFiled: October 28, 2009Date of Patent: May 17, 2011Assignee: Sikorsky Aircraft CorporationInventors: Peter Xavier Palcic, Todd Garcia, Yuriy Gmirya

Patent number: 7102773Abstract: A method for multicasting of documents. The host receives the document data, including a number of documents to be created. The host then divides the number of documents to be created into batches and formats the data into a print job. The information about the batches and assignments to printers in the cluster is embedded into the print job. The host then transmits the print job for production of the documents.Type: GrantFiled: July 19, 2000Date of Patent: September 5, 2006Assignee: Sharp Laboratories of America, Inc.Inventors: Jack Van Oosterhout, Octavio Todd Garcia
